Malicious package

@shiftmarkets/shift-exchange-rootnpm

Advisory published Updated

@shiftmarkets/shift-exchange-root is a confirmed malicious npm package (MAL-2026-12509) that steals credentials and exfiltrates sensitive data (malicious versions 1.9.9, 2.9.9, 3.9.9). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @shiftmarkets/shift-exchange-root (npm)

MAL-2026-12509
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @shiftmarkets/shift-exchange-root

What this malware does

On npm install, the package's postinstall hook (scripts.postinstall: 'node dist/recon.js || true') automatically runs dist/recon.js, which collects the installer's hostname, username, SUDO_USER, home directory, current working directory, internal IPv4 addresses for each network interface, DNS domain (via execSync of dnsdomainname), the full sorted list of process.env variable names, CI indicators, and the npm user-agent/cache, and POSTs this JSON payload to http://138.68.108.20:80/cb over cleartext HTTP. The env-var name list is additionally filtered by a credential regex (AWS|GCP|GOOGLE|AZURE|NPM|NODE_AUTH|DOCKER|KUBE|VAULT|TOKEN|SECRET|KEY|PASS|CRED|GITHUB|GITLAB|SSH) and shipped as a separate credential-shaped-name inventory. The destination is a bare IP unaffiliated with the @shiftmarkets scope's publisher, contacted over plain HTTP. The package's main entry (dist/index.js) exports only trivial math helpers (sum/subtract/multiply/divide) that do not match the @shiftmarkets/shift-exchange-root name, and a header comment in the recon script labels the collection as 'NON-SENSITIVE telemetry only... env var NAMES (never values)' — a cover story that contradicts the actual collection of host identity, internal network topology, sudo user, and credential-shaped env key inventory.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for @shiftmarkets/shift-exchange-root (3 malicious versions).

  2. If you installed it — respond

    @shiftmarkets/shift-exchange-root is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If @shiftmarkets/shift-exchange-root was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. @shiftmarkets/shift-exchange-root on npm has been identified as a malicious package (versions 1.9.9, 2.9.9, 3.9.9 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
